August 12, 2015 - Celiac Disease Flashcards
Culprits of Gluten
Wheat, Rye, and Barley
Genetic Factors for Celiac Disease
HLA-DQ2 and/or DQ8
You need one of these two genes to have celiac disease.
The DQ2 and DQ8 genes create receptors to which gluten peptides tightly bind, which activates T lymphocytes which cause the release of cytokines and damage the tissue.
HLA-DQ2 and DQ8
At least one copy is needed for celiac disease. However, these are common in around 30% of the population, but only 3% of these people will develop the disease so the presence does not equal the condition.
Celiac disease occurs in approximately 1% of people.
Celiac Disease Complications
- Anemia (from iron deficiency)
- Osteoporosis (from vitamin D deficiency)
- Malnutrition (less SA for absorption)
- Risk of cancer
Celiac Disease Diagnosis
Order an anti-endomysial antibody (IgA EMA) test. - tTG Serology
It is also important to order an IgA test to ensure normal levels of IgA are being produced.
When to Screen for Celiac Disease
Whenever you suspect any signs/symptoms of it. It is a cheap blood test.
Response to Gluten-Free Diet
Most (95%) improve dramatically in two weeks
5% fail to improve after 2 years, however it is often due to intentional or inintentional “cheating” in their diet.
